Industry Loss Warranty Trigger Verifier using LangChain and LangGraph
Industry Loss Warranties depend on reliable, tamper-evident verification of physical and monetary catastrophe loss thresholds. You will build a stateful verification pipeline using LangChain and LangGraph to correlate multi-source weather sensor feeds with index loss reporting. Achieve zero false-positive trigger executions and sub-second validation latency across catastrophe scenarios.
What you are building
The core problem, expected build, and operating context for this challenge.
Build a stateful multi-step agent workflow in LangGraph to verify Industry Loss Warranty (ILW) index triggers.
How work is evaluated
Assess trigger execution accuracy and verify absence of false positives across storm scenario test suite.
Shared data for this challenge
Review public datasets and any private uploads tied to your build.
How submissions are scored
These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.
zero_false_positives
No contract triggering when actual industry loss is below threshold.
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
validation_latency_ms
Time taken to complete graph evaluation in milliseconds • target: 500 • range: 0-1000
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
What you should walk away with
